Application tilled tannsry 2 To all whom it may concern.

Be it known that I, HAsmr VINCENT BALL, a citizen of the United Suites, residing at Montreal, Province of Qneheo, and Dominiion of Canada, have invented certain new and useful-Improvements in Web Joining and Posting Devices, fully described end represented in the following specification and the accompanying drawings, forming" a part of the same.

This invention relates to certain improve ments in Web joining or pasting devices.

it is the especial object the present invention to provide on effective construction by means of which the end of the spare or inactive web roll may be secured to the Web of running web roll when the latteris at or near the exhaustion point, theconstrnction being o. simple one and one easily manipulated, and which will produce positive and effective joining of the webs.

A further object of the invention is to produce such s construction which may he resdily installed in s web mschi'ne, es s. Web printing machine, Without changing or redesigning the machine, end which will be simple and inexpensive to make and keep in order. 1

With these and other objects not specifiicslly referred to, the invention consists in certain novel ports, arrangements and comemotions, at detailed description of which will he given; in connection with the sccompsnying drswings and the novel features theceof pointed out in the claims hereunto snnesed. V

in these drawings Figmrcl is at side elevation, portly broken sissy, showing the improved pasting device in connection with so much of at web toll machine as is necessary for on understood ins; of the invention.

Figure 2 is a. broken end vicw'ot the construction shown in Fig. 1.

Referring now to thew drawings Whiclii illustrate s' preferred embodiment of the in vention, the improved pasting device has been illustrated as employed in e. construc tion in which the running end the inactive rolls are carried in fixed bearings, the wet;

in use running from. s roll in either one of Referring hrst to the con.

the bearings. strnction shown in full lines in Fig. 1, "there is hovvn on inactive roll 1, mounted in heat ings 3., located in lower brackets 2-5 secured s, was. semi so. meets.

to the side frames 4:! of the machine. Above the lower brackets 3 end at one side there-01; ore upper lorockcts 5 in which are provide heorin s 6 for s second roll, 7, this second roll losing indicated by the full lines as shout to expire.

Secured to the lower part of the frames s are c pair of brackets 8, having depending legs Elsccurcd to the door or other suitable support by bolts 10. These brackets form supports for studs, 11, on which are pivotsl- 1y mounted it pair of frames 12, 13 connected at their upper ends by at cross bar 14;. One of these sides frames, ss frome 12, is curved, as indicated at 15 so as to extend around and clear the usnsl -roll broking mechanism 16 for the roll in the lower bearings 3. T he frames 12, 13 extend tlclow the pivoted point to torn supports 17, in which may be secured Weights 18 so thct normally the frame will swing; in on o right position. as shown in dotted lines #1619 in Fig. 1, when the device is not in use.

The upper ends of he tfrsmo shovstlie cross bar 14, before referred to, is fotmed with s pair 02. hubs 20, in which is mounted at shaft 21 extending between the frames and carrying it posting roll 22. One end of this shaft is provided with o. messes with I which co-operstes a, pawl 2t pivoted st 25 in the side frame 6, the ohiect of this construction being to prevent the backward rotation of the posting roll after the wehThas been secured thereto.

The operation of the device is as follows Assuming that the web. from the inactive roll 1 in the lower hearings 2 is tohe secured to the Web of" the csrfliring roll 7 'in the'npper brackets 55, the operator secures the end of the vveh W from the-ins active roll 1 to the posting roll 22 by some hand which is ensily broken, such cs grease put on the roll 22, the pivoted frames being in the position shown in dotted. lines in Fi 1, which in the articular construction siiovvn would give the operator room to. do this. If desired of course, the frames could be swun fort we to the right in Fl 1, if additions spscewss required for con- ,venience in attaching thewebs. v The frames with the new web attached are then swun to the left as shown in dotted lines, on

the end of the new web, to thsoutcr surface of which. it suitable adhesive, cs posts, has been supplied, will he brought into comtact with the expiring web from the roll 7 at the desired time, the two webs being squeezed between the roll 22 and co-operating abutment roll 26 over which the running web is led to the printing or other machine and which is secured inthe frames 4, before referred to. .With this construction the two webs may be brought together with sutficient pressure to ensure an effective pasting and after the paste is made the expiring web may 'be severed or broken in any suitable manner.

web marked W from an almost expired roll indicated by the letter E in the lower bearings 2, to the web of a full roll, shown in dotted lines marked 27 in the upper bracket 5, the new roll 27 has paste applied thereto at some point upon its surface. This roll is their rotated in any desired or usual manner and the frame may be swung to cause the expiring web VV' to come into contact with the pasted surface of the roll 27. The two webs then pass between the rolls 22 and 26 and the paste made, after which the web W may 'be sevcred or broken as usual.

With this construction a very simple and effective web joining device has been produced, one which can be readily installed. in a machine, and is simple and inexpensive to make and easily operated.

While a preferred form of the device has been shown, it will be understood that various changes may be made 'in the construe tion of the device and that the invention is not to be, restricted to the exact construetion and arrangement of parts shown and described, nor to the mrnngenient of web rolls shown.

What I claim is:

1. In a web pasting device, the combimrtion of a support for 21. running roll and for a spare roll, of a swinging frame mounted to swing so as to bring a new web in contact with an expiring web, a pasting roll carried by the frame, and a co-operab ing abutment for the posting roll between which and the roll the two webs run and When it is desired to write an expiring,

effect a paste.

2. In a web pasting device, the combinm tion of a support for a running roll and for a spare roll, a frame mounted to swing toward and from the web running from either roll, a pasting roll carried by the frame, a (to-operating abutment for the push ing roll between which and the roll the two webs run and effect a paste, and means for returning the frame to position after it has been swung to make the paste.

3. In a web pasting device, the combination of a support fora running roll and for a spare roll, a frame including spaced side arms pivoted to swing toward and from the web running from either roll, weights on the arms below their pivot points, :i pasting roll carried between the arms above the pivot oints and a cooperating abutment roll etween which and the pasting roll the two Webs ass.

In testimony wiereof, I have hereunto set my hand.
